Orion Mars Filter – 1.25-Inch Supply

Orion Mars Filter – 1.25-Inch

The custom-designed Orion Mars Observation filter enhances contrast of virtually all surface features. Dielectric coatings transmit violet/blue (615nm) wavelengths where detail is rich, while blocking overbearing yellow/green (515nm to 615nm) wavelengths. Polar icecaps appear more sharply defined, and differences in landscape shading are nicely resolved. Polar hazes and cloud cover become visible. The filter’s high transmission makes it effective even in small telescopes. This custom-engineered Orion telescope filter comes with a protective plastic case.

Manufacturer’s Warranty: Limited Warranty against defects in materials or workmanship for one year from date of purchase. This warranty is for the benefit of the original retail purchaser only.
